contact lens fitting & evaluations

Finding the right pair of lenses is a lot like finding the love of your life. No really! Sometimes it takes years to find the perfect fit with the most satisfying vision and when that happens you don't ever want to let it go. Dr. Byers has the patience to work with you until you have found that perfect fit!Daily Wear Soft Contact LensesDisposable lenses: Replaced every two weeks, or dailyFrequent replacement lenses: Replaced monthly or quarterlyTraditional (reusable) lenses: Replaced every six months or longerExtended Wear lenses: Several extended wear lenses are FDA-approved for up to seven days of continuous wear, and at least two brands of silicone hydrogel EW lenses — Air Optix Night & Day (CIBA Vision) and PureVision (Bausch + Lomb) — are approved for up to 30 days of continuous wear.Rigid Gas Permeable Hard Contact LensesGas permeable contact lenses are rigid lenses made of durable plastic that transmits oxygen. These lenses also are called GP lenses, rigid gas permeable lenses, RGP lenses and oxygen permeable lenses. GP contact lenses are rigid, but they shouldn't be confused with old-fashioned hard contact lenses, which are now obsolete.Bifocal Contact LensesAre MultiFocal Contact Lenses right for you? Read all about it at AllAboutVision, a leader it eye care resourcesBifocal contact lenses are designed to provide good vision to people who have a condition called presbyopia. The main sign that you're developing presbyopia is that you need to hold menus, newspapers and other reading material farther from your eyes in order to see it clearly.Bifocal contact lenses come in both soft materials and rigid gas permeable (GP) materials. Some can be worn on a disposable basis. That means you have the convenience of throwing the lenses out at specified intervals (even daily, in some cases) and replacing them with fresh, new lenses.Several lens manufacturers offer multifocal contact lenses made of silicone hydrogel material. These lenses allow significantly more oxygen to reach the cornea than conventional soft lenses for greater wearing comfort, and are available for both daily wear and extended wear.Brands of multifocal silicone hydrogel contacts include Acuvue Oasys for Presbyopia (Vistakon), Air Optix Aqua Multifocal (Ciba Vision), Biofinity Multifocal (CooperVision) and PureVision Multi-Focal (Bausch + Lomb).Toric Contact LensesToric contact lenses are made from the same materials as regular ("spherical") contact lenses, so they can be either soft or RGP. The difference is in the design of the lens.Toric lenses have two powers in them, created with curvatures at different angles (one for astigmatism, the other for either myopia or hyperopia). There's also a mechanism to keep the contact lens relatively stable on the eye when you blink or look around. To provide crisp vision, toric contact lenses cannot rotate on your eye.
